there are all sorts of color wiring diagrams posted in the electrical section for the 60-66 and 67-72 truck
not sure why anyone would spend $18 plus $10 shipping for something that is probably a reprint from this website
not much for wiring on the pre- 60 trucks, pretty much everything wires off the headlight switch and top regulator screw
if you have a radio, heater or electric wipers, it was most likely a dealer addon and wired by that dealer with an inline fuse
rarely do you have the factory 3 fuse panel: it'd have to come factory with all 3 options
these trucks are pretty basic, no fuse box, except 1 fuse for instrument panel lights (C)
look at post
#7 in this thread, even back then gm turn signal wire colors followed the newer vehicles
GreasyLikeaBurger's wiring won't be anything near stock, as it's 12v without the generator/regulator
